On some extremal problems in certain harmonic function spaces of several variables related to mixed norm spaces
Distance estimates harmonic function unit ball Bergman spaces
2012/5/9
We provide some new estimates for distances in harmonic function spaces of several variables related to mixed norm spaces.Some of them extend previously known assertions in this direction in the unit ...
On some extremal problems in spaces of harmonic functions
Bergman spaces distance estimates extremal problems harmonic functions
2011/9/19
Abstract: We give solutions to some extremal problems involving distance function in mixed norm spaces of harmonic functions on the unit ball of R^n.
Some remarks on extremal problems in weighted Bergman spaces of analytic functions
weighted Bergman spaces of analytic functions Complex Variables
2011/9/19
Abstract: We prove some sharp extremal distance results for functions in weighted Bergman spaces on the upper halfplane.We also prove such results in the context of bounded strictly pseudoconvex domai...
Tchebycheff systems and extremal problems for generalized moments: a brief survey
Tchebycheff systems extremal problems brief survey Optimization and Control
2011/9/14
Abstract: A brief presentation of basics of the theory of Tchebycheff and Markov systems of functions and its applications to extremal problems for integrals of such functions is given. The results, a...
Generalization of some extremal problems on non-overlapping domains with free poles
Geometric Topology Complex Variables non-overlapping domains free poles
2011/8/25
Abstract: Although much research has been devoted to extremal problems on non-overlapping domains little is known about all solutions of this problems. We generalized some of this problems on the case...
